An IoT Approach for Wireless Sensor Networks Applied to e-Health Environmental Monitoring

Abstract

This paper presents an Internet of Things (IoT) approach for monitoring temperature and relative humidity applied to product maintenance in hospitals or pharmaceutical entities. Our goal is to integrate a low-cost and scalable network of smart sensors capable of mapping large areas in real-time. In this article, we provide a comprehensive insight into the technologies that compose the IoT architecture: (i) the node layer composed of Wireless Sensor Network (WSN), (ii) the local management layer of the WSN and (iii) the cloud-based layer for enabling remote monitoring. To the date, our IoT system has been working during (8) months in The Hospital Universitario San Ignacio, a 4th level university hospital located in Bogota, Colombia. Here, we present a field report of this work-in-progress system.
